NCP3063BDR2G

NCP3063BDR2G is an NCP3063 series step-up/down/inverting switching regulator. It is a higher frequency upgrade to the popular MC34063A and MC33063A monolithic DC-DC converters. This device consists of an internal temperature-compensated reference, a comparator, a controlled duty cycle oscillator with an active current limit circuit, a driver, and a high current output switch. It was specifically designed to be incorporated in step-down, step-up, and voltage-inverting applications with a minimum number of external components. The applications include step-down, step-up, and inverting supply applications, high-power LED lighting, and battery chargers.
